.Nd Broadcom BCM43xx IEEE 802.11b/g wireless network driver
|
|
|
|
.Sh SYNOPSIS
|
|
|
|
To compile this driver into the kernel,
|
|
|
|
place the following lines in your
|
|
|
|
kernel configuration file:
|
|
|
|
.Bd -ragged -offset indent
|

|
.Cd "device wlan_amrr"
|
|
|
|
.Cd "device firmware"
|
|
|
|
.Ed
|
|
|
|
.Pp
|
|
|
|
Alternatively, to load the driver as a
|
|
|
|
module at boot time, place the following line in
|
|
|
|
.Xr loader.conf 5 :
|
|
|
|
.Bd -literal -offset indent
|
|
|
|

|
|

|
.Sh DESCRIPTION
|
|
|
|
The
|
|
|
|
.Nm
|
|
|
|
driver provides support for Broadcom BCM43xx based
|
|
|
|
PCI/CardBus network adapters.
|
|
|
|
.Pp
|
|
|
|
It supports
|
|
|
|
.Cm station
|
|
|
|
and
|
|
|
|
.Cm monitor
|
|
|
|
mode operation.
|
|
|
|
Only one virtual interface may be configured at any time.
|
|
|
|
For more information on configuring this device, see
|
|
|
|
.Xr ifconfig 8 .
|
|
|
|
.Pp
|
|
|
|
This driver requires firmware to be loaded before it will work.
|
|
|
|
The
|
|
|
|
.Pa ports/net/bwn-firmware-kmod
|
|
|
|
port needs to be installed before
|
|
|
|
.Xr ifconfig 8
|
|
|
|
will work.
|
2010-02-26 00:37:49 +00:00
|
|
|
Most cases you need to use bwn_v4_ucode module but if you are a
|
|
|
|
LP (low power) PHY user please uses bwn_v4_lp_ucode module.

2010-09-14 23:27:06 +00:00
|
|
|
Users of older Broadcom chipsets (BCM4301, BCM4303 and BCM4306 rev 2)
|
|
|
|
must use
|
2010-09-11 21:49:28 +00:00
|
|
|
.Xr bwi 4
|
2010-09-14 23:27:06 +00:00
|
|
|
because the v4 version of the firmware does not support these chips.
|
|
|
|
The newer firmware is too big to fit into these old chips.

.Sh EXAMPLES
|
|
|
|

|
|
|
|
ifconfig wlan create wlandev bwn0 inet 192.168.0.20 \e

|
|
|
|
.Dq Li my_net :
|
|
|
|
.Pp
|
|
|
|
.Dl "ifconfig wlan create wlandev bwn0 ssid my_net up"
|
|
|
|
.Pp
|
|
|
|
Join a specific BSS network with 64-bit WEP encryption:
|
|
|
|
.Bd -literal -offset indent
|
|
|
|
ifconfig wlan create wlandev bwn0 ssid my_net \e
|

.Sh LOADER TUNABLES
|
|
|
|
Tunables can be set at the
|
|
|
|
.Xr loader 8
|
|
|
|
prompt before booting the kernel or stored in
|
|
|
|
.Xr loader.conf 5 .
|
|
|
|
.Bl -tag -width indent
|
|
|
|
.It Va hw.bwn.msi_disable
|
|
|
|
This tunable disables MSI support on the hardware.
|
|
|
|
The default value is 0.
|
|
|
|
.It Va hw.bwn.usedma
|
|
|
|
This tunable enables DMA operations on the hardware.
|
|
|
|
If the value is 0, PIO mode would be used.
|
|
|
|
The default value is 1.

.Sh CAVEATS
|
|

Some LP PHY devices have DMA operation problems that in that case try to
|
|
|
|
use PIO mode.
